[0011] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when punching a hole in the fiber tube, one end of the fiber tube is inserted into the opening on one side of the mounting frame, and the height of the support plate is adjusted so that the support plate supports the bottom of the fiber tube. The adjusting frame is moved under the drive of the adjusting electric cylinder, and the connecting rod and the rotating clamping rod are clamped through the annular groove on the connecting rod. Subsequently, the rotating clamping rod is driven to rotate by the rotating motor, and the rotation of the rotating clamping rod drives the connecting rod to rotate. The connecting rod causes the adjusting disk to rotate, and the several arc grooves provided on the adjusting disk cause the clamping rod to drive the moving rod to move toward the direction of the opening. Then, through the rotation of the adjusting disk, the several moving rods can be synchronously controlled to move synchronously toward the fiber tube placed at the opening, so that the several positioning members provided can position and clamp the fiber tube around the opening.

[0012] In the present invention, when the moving rod moves toward the direction of the opening, the moving rod will drive the shell to move toward the fiber tube at the opening through the pushing frame, and the measuring frame will move synchronously toward the direction of the opening under the action of the connecting spring. At this time, after the measuring frame contacts the outer wall of the fiber tube, the measuring frame will not continue to move.

After the measuring frame stops moving, the shell will continue to move toward the direction of the fiber tube under the continuous movement of the pushing frame. After the shell moves, the expansion plates on both sides of the positioning block will be retracted and expanded toward the direction of the fiber tube under the drive of the push plate, thereby fixing the outer wall of the fiber tube, and three-point positioning is performed by the positioning block and the two arranged expansion plates to improve the stability of the fiber tube fixation.

[0013] In the present invention, when the fiber tube is subjected to annular punching, the position of the measuring rod is first observed, and then the transmission is adjusted. At this time, as the mounting frame rotates, the rotating bevel gear is driven to rotate through the transmission bevel gear. After the rotating bevel gear rotates, the transmission rod is rotated, and the transmission rod rotates the rotating rod through the transmission belt. The rotating rod rotates and drives the rotating frame to rotate. At this time, the rotating frame drives the eccentrically arranged mobile frame to rotate, and the mobile frame reciprocates to pull the arranged connecting frame to move, thereby causing the pressure block at the other end of the connecting frame to move toward the direction of the fiber tube, and the fiber tube is drilled by the drill on the pressure block. The setting position of the measuring rod is observed and then the diameter of the fiber tube is observed, so that when the transmission is adjusted to rotate the mounting frame, the speed change of the rotating rod when the rotating rod rotates can be adaptively adjusted according to the diameter of the fiber tube when the equal-spaced annular holes are punched. The adjusting block is moved in the arc limiting groove through the arranged arc limiting groove. When the adjusting block moves, the adjusting plate is pulled to move, so that the adjusting plate can pull the moving frame to move, thereby adjusting the distance moved by the pressure block on the support frame, thereby adjusting the depth of the fiber tube punching.

At this time, as the mounting frame 13 rotates, the rotating bevel gear 54 is driven to rotate through the transmission bevel gear 43. After the rotating bevel gear 54 rotates, the transmission rod 53 is rotated. The transmission rod 53 rotates the rotating rod 51 through the transmission belt 56. The rotation of the rotating rod 51 drives the rotating frame 57 to rotate. At this time, the rotating frame 57 drives the eccentrically arranged moving frame 58 to rotate.

[0022] The use method and advantages of the present invention: The use method of the variable diameter fiber punching positioning device, the working process is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown: when punching a hole in the fiber tube, one end of the fiber tube is inserted into the opening 14 on one side of the mounting frame 13, and the height of the support plate 26 is adjusted so that the support plate 26 supports the bottom of the fiber tube. The adjusting frame 213 is moved under the drive of the adjusting electric cylinder 212, and the connecting rod 210 is engaged with the rotating clamping rod 29 through the annular groove 211 on the connecting rod 210, and then the rotating clamping rod 29 is driven by the rotating motor 28 to rotate, and the rotating clamping rod 29 rotates to drive the connecting rod 210 to rotate, and the connecting rod 210 rotates the adjusting disk 21, and the arc grooves 22 provided on the adjusting disk 21 make the clamping rod 24 drive the moving rod 23 to move toward the direction of the opening 14, and then the rotation of the adjusting disk 21 can synchronously control the moving rods 23 to synchronously move toward the fiber tube placed at the opening 14, so that the provided positioning members 3 can position and clamp the fiber tube around the opening 14; When the moving rod 23 moves toward the direction of the opening 14, the moving rod 23 will drive the sleeve 32 to move toward the fiber tube at the opening 14 through the pushing frame 31, and the measuring frame 33 will move toward the direction of the opening 14 synchronously under the action of the connecting spring 37. At this time, after the measuring frame 33 contacts the outer wall of the fiber tube, the measuring frame 33 will not continue to move. The diameter of the fiber tube is judged by the position of the measuring rod 35 on the measuring frame 33 in the measuring groove 34, thereby facilitating the subsequent punching operation of the fiber tube. At the same time, the elastic clamping block 36 on the measuring rod 35 is engaged with the measuring groove 34 to limit the measuring frame 33. When the measuring frame 33 stops moving, the sleeve 32 will continue to move toward the direction of the fiber tube under the continuous movement of the pushing frame 31. After the sleeve 32 moves, the expansion plates 39 on both sides of the positioning block 38 will be retracted and expanded toward the direction of the fiber tube under the drive of the pushing plate 310, thereby fixing the outer wall of the fiber tube. The positioning block 38 and the two expansion plates 39 are used for three-point positioning to improve the stability of the fiber tube fixation. When the fiber tube is subjected to annular punching, the position of the measuring rod 35 is first observed, and then the transmission 52 is adjusted. At this time, as the mounting frame 13 rotates, the rotating bevel gear 54 is driven to rotate through the transmission bevel gear 43. After the rotating bevel gear 54 rotates, the transmission rod 53 is rotated. The transmission rod 53 rotates the rotating rod 51 through the transmission belt 56. The rotation of the rotating rod 51 drives the rotating frame 57 to rotate. At this time, the rotating frame 57 drives the eccentrically arranged moving frame 58 to rotate. The moving frame 58 reciprocates and pulls the connecting frame 511 to move, thereby causing the pressing block 59 at the other end of the connecting frame 511 to move toward the direction of the fiber tube. Through the drill on the pressing block 59, the fiber tube is drilled. The hole driller 510 performs a drilling operation on the fiber tube, observes the setting position of the measuring rod 35 and then observes the diameter of the fiber tube, thereby adjusting the transmission 52 to rotate the mounting frame 13, so that the speed of the rotating rod 51 changes, so that it can adaptively adjust when making evenly spaced circular holes according to the diameter of the fiber tube, and the arc-shaped limit groove 512 is set to make the adjustment block 513 move in the arc-shaped limit groove 512, and when the adjustment block 513 moves, it pulls the adjustment plate 514 to move, so that the adjustment plate 514 can pull the movable frame 58 to move, and then adjust the distance that the pressure block 59 moves on the support frame 25, thereby adjusting the depth of the fiber tube punching.
